Hello, my name is***** will assist you.

Locate part 34 in the diagram. Unplug the black and yellow wire from it and see if the spark returns to the engine. If so, replace the rev limiter. If it does not, you are going to need to test the voltage coming from the stator on the green/white and the white/green wires. It needs to be over 150 V AC when cranking.
